CSCee13412 - Support for Sending RedirectNumber IE in H225 SETUP

Hi, I have the following problem. May be it is regarding this Bug. A redirected call comes from CUCM to H323 VGW and leave Pots Dialpeer BRI S0 ISDN as a Q931 Setup Message. But redirected number is not seeing in Outgoing Q931 Setup, only the Calling and Called Party Number.

It should be transmitt also the Redirected Number.

Any help are appriciate.

Thanks in ahead.

CSCee13412 - Support for Sending RedirectNumber IE in H225 SETUP

Hello Armin,  Please confirm the call flow. I think i hear you saying the call flow is:


A few questions:

  • Is redirecting IE presented from IOS1? (debug h225 asn1)
  • Is CUCM configured to receive redirecting number inbound on h323 gateway config for IOS1? (ccmadmin, check CUCM SDI/SDL traces)
  • Is CUCM configured to send redirecting number outbound on h323 gateway config for IOS2? (ccmadmin, check CUCM SDI/SDL traces)
  • Does IOS2 receive redirecting number from CUCM (debug h225 asn1)

This problem breaks down into if CUCM is sending it and then if IOS is passing it from h.323 to ISDN BRI leg.  Debugs will help to confirm where redirecting number is being dropped.

You may consider opening a Cisco TAC case for additional assistance. I recommend starting with Communications Manager.
